Hi Martin, thanks for doing this Q&A sessions really cool stuff! I have a very specific questions regarding the functionalities of API calls. I want to make an API call from an ethereum smart contract to check if a payment from User A to User B has occured. Lets say I have a website/webapp that brings A and B together. How can I make sure that an external party (the smart contract) is authorized to 1. see that a payment occured 2. get the details of the transaction I am assuming that the smart contract can store the necessary API authentification tokens I know that is a bit of a broad question buy help is appreciated. Cheers, Markus
